To all whom 'it may concern.'

Be it knownthat I, JOHN W. COOPER, citizen of the United States, residing at Dorchester Station, Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sash-Hangers, of which the following is a specification. A

The present invention appertains to window frames and more particularly to the sash hangings or fixtures, whereby the sashes may slide freely in the frame and be turned into a horizontal position or removed from the frame as may be required either for ventilation, cleaning orto admit of repairs.

The invention has for its object to conceal from view the cord or like connection between the sash and its counterbalance, also to provide a novel construction of window frame and sash securing means which will admit of the sash swinging freely when it is required, from a vertical into a horizontal position, or vice versa.

The invention also relates to novel means for securing the counterbalance sash cord against actual displacement after the sash has been moved into a position to be disconnected from the frame, thereby admitting of the sash being conveniently and safely removed or replaced in the frame, the lock means cooperating with the counterbalance sash cord being actuated by the movements of the sash.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment lis shown in the accompanying drawings, in which:

Fig. 10 is a detail view of the stop, trip and runner cooperating with the `lower sash. Fig. 11 is a detail perspective view of a side portion of the upper and lower sashes, showing the runners, sash cords and pulleys therefor. Fig. 12 is a sectional view of the upper portion of the guide strip and the stile of the lower sash to which said guide strip is attached, showing means for preventing vertical displacement of the guide strip.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The window frame may be of usual con struction with the exception of the jambs, which are provided with vertical grooves 1 and 2, for the sash runners 3 and 4 to operate in, said jambs being further altered upon their sides facing the window opening to admit of the sashes being readily removed.

. The portion of the jamb 5 facing inward is cut away to receive the lower sash 6 and is provided with a vertical groove 7 in which operates a guide strip 8 attached to the side stile of the sash 6. The outer portion of the jamb 5 is thicker than the inner portion to receive the upper sash 9, the same sliding in ways formed between a strip 10 and a facing strip 11. The stripv 10 terminates at its lower end at a point to admit of the upper sash clearing the same when moved to its lowest position, whereby said sash may be turned into horizontal position, as indicated by the dotted lines in Fig. 4. The lower sash 6 o crates in guides formed by the strip 10 anc shoulder 12 and the groove 7 and guide strip 8. The shoulder 12 runs the entire length of the jamb 5 and is located at the outer vertical edge of the inner reduced portion of the jamb 5. The guide strip 8 is adapted to have an edge portion project beyond the outer edge of the side stile of the sash 6 and enter the groove 7 and thereby prevent inward displacement of the sash 6 under normal conditions. is connected to the side stile of the sash 6 in a manner to admit of its outer edge portion being projected beyond the outer edge of the sash so as to enter the groove 7 or to be withdrawn about flush with the outer edge of the sash so as to clear the groove 7 and the inner face of the reduced portion of the jamb 6 so that the sash 6 may be lowered into hori- Zontal position, as indicated by the dotted lines in Fig. 4, or removed from the window frame, as may be desired. Links 13 connect the guide strip 8 with the stile of' the sash and occupy an approximately horizontal position when the outer edge of said guide strip is projected beyond the outer edge of the sash. When the guide strip 8 is moved vertically, the links 13 turn upon their pivotal connections with the sash, stile and strip and assume an upright position, with the result that the outer edge of said guide strip is withdrawn within the outer edge of the stile of the sash, thereby admitting of the latter being moved inward with reference to the window frame. The links 13, as shown most clearly in Fig. 3, are let into recesses 14 formed in the face of the sash stile so that the guide strip 8 may come in close contact with the outer face of said stile to exclude wind, dust and inclement weather.

The sash runners 3 and 4 are of similar formation, the only difference being that the web or plate of the runner 3 is slightly wider than the corresponding part of the ruimer 4 to allow for the extra thickness of the outer portion of the jamb 5, as indicated most clearly in Fig. 3. Each runner consists of a plate or web 15, a socket 16 at one edge thereof and widened at its lower' end, as shown at 17, and a rounded projection 18 at the opposite edge and preferably at the lower corner and formed with a groove 19. The web or plate 15 operates in either the groove 1 or the groove 2. The socket 16 is adapted to travel upon the inner side of the j amb 5, whereas the projection 18 occupies a position upon the outer side of said jamb 5 and makes connection with either the sash `6 or the sash 9. The sash cord 20 has an end portion passed through the socket 16 and its extremity knotted or otherwise thickened so as to fill the widened portion 17 of the socket and prevent withdrawal of the cord after being properly engaged with the socket 16.'

The guide strip 8 The opposite end of the sash cord is weighted or counterbalanced in the accustomed way, as shown at 21, and said sash cord passes over a pulley 22 at the upper end of the jam h. The pulley 22 may be of any design and relative arrangement, as indicated most clearly in Figs. 4 and 11, the former showing a sheave pulley set in a block and the latter illustrating a screw pulley to be let into the cap piece or other convenient portion of the window frame. The sash cord is located wholly within the space or boxingof the jamb and is concealed from view. The. slots 1 and 2 are comparatively narrow and admit of the webs or plates 15 of the runners moving freely therein. The mounting of the sash runners 3 and 4, in the manner set forth, prevents displacement thereof and insures correct position thereof when removing or placing the sashes in position, which would not be the case if a portion of the sash and cord were exposed in the usual way.

lWhen it is required to turn either sash into horizontal position or to remove the same from the window frame, it is necessary that the sash be moved to its lowest position in the frame in order that the cooperating sash runners 8 or 4 may be held and thereby prevent their upward displacement when relieved of the weight of the sash. ln the case of the uppersash9 itis doubly necessary that the same be moved to its lowest position in order to clear the parting strip 10. ti/'hen the upper sash 9 is moved to its lowest position in the frame, a stop 28 engages over the runner 3 and holds the same against upward displacement, after the sash 9 has been swung inward at its upper end. r1`he stop 23 consists of a pressure head 24 having an inclined edge 25 and a tang 26 from opposite faces of which pins 27 and 28 project. This stop is let into a mortise or recess 29 formed in the. mating faces of the amb 5 and facing strip 11. rlhe pin 28 is adapted to project across the path of the runner 3 and is acted upon by a spring mounted upon the pin 27 and exerting a pressure upon the tang 26 to force the pressure head 24 and the pin 28 inward. l hen the sash 9 is in normal position, the

outer face of its stile bears against the inclined edge 25 of the pressure head 24 and holds the same outward against the tension of the spring 30, thereby withdrawingI the pin 28 from thepath of the runner 3 so that the sash 9 may move freely up and down in the frame, but when said sash 9 is lowered to clear the parting strip 10 and to bring the, runner 3 below the stop 28, and is then moved inward, pressure is removed from the head 24, and the spring 8() expanding forces the head 24 and pin 28 inward, and said pin 28 extending across the path of the runner 3 prevents upward movement thereof when the sash. is swung inward or removed from the frame. When the sash 9 is replaced and turned into vertical position, it comes in contact with the inclined edge 25 of the pressure head 24 and moves the latter outward, thereby withdrawing the pin 28 from the path of the runner 3 so that the sash is free to move upward.

For holding the runner 4 in its lowest position when the sash 6 is swung inward or removed from the frame, a stop 31 is provided and consists of a dog pivoted at 32 and provided with opposite projections 33 and 34, the latter adaptedvto engage over the runner 4, as indicated in Fig. 10. The stop or dog 31 is pivoted to the side of the jamb 5 facing the recess, bucket or space of the side piece of the frame. The stop or dog is weighted and when free occupies a position with the projection 34 in the path of the runner 4 so as to hold the same against upward displacement. A trip 35 is adapted to be projected across the path of the extension 33 and move the dog so as to withdraw the projection 34 out of the path of the runner 4 so that the sash 6 may be free to move up and down. The trip 35 is carried by means of a flat spring 36, whichis placed in the lower portion of the groove 7 and secured at one end to the j amb 5. When the guide strip 8 presses against the free end of the spring 36, the strip 35 is projected into engagement with the part 33 and moves the stop or dog 31 so as to withdraw the projection 34 thereof out of the path of the runner 4. TWhen the strip 8 is withdrawn from the groove 7 preliminary to swinging the sash 6 inward or removing it from the window frame, pressure is removed from the spring 36, and its free end moving towards the window opening, withdraws the trip 35 from engagement with the projection 33, thereby permitting the dog 31 to swing into the position indicated by full lines in Fig. 10 and over the runner 4 so as to hold the same from vertical displacement. The engaging portions of the trip 35 and projections 33 are curved or inclined to ride one upon the other to effect movement of the dog so as to withdraw its projecting part 34 from the path of the runner 4 when the trip 35 is pressed into position by engagement of the guide strip 8 therewith.

The castings 37 fitted to the lower corners of the sashes, as indicated most clearly in Fig. 5, consist of fianged plates 38 having a depression 39 made rounding at its upper end and open at its lower end, the upper closed end of the depression 39 having a rib 40 which is adapted to enter the annular groove 19 of the rounded projection 18 and thereby form interlocking means to prevent separation of the parts when assembled. After the rounded projection 18 has been slipped into the depression 39 from below, the pin 41 is passed through openings in the vertical walls of the depression 39 and in the vertical flange of the casting, said pin also entering the annular groove 19 of the projection 18 and supplementing the action of the rib 4() in retaining the parts in position. Before either sash may be removed from the window frame, it is necessary that the pins 41 be removed from the castings so that the latter may slip from the rounded projections 18.

To prevent vertical movement of the guide strip 8 in the operation of the sash, it is necessary to provide securing means. As shown in Fig. 12, a catch is provided and secured to the stile of the sash 6 and has its upper end bent to engage over the upper end of the strip 8. The stile of the sash 6 is recessed to admit of pressing the catch to one side to clear the guide strip 8 when it is required to move the same to admit of the strip 8 clearing the groove 7 when it is required to move the sash inward.
